The Art of Aging, Whiskey... How Long Should It Age to Enhance Its Flavor?

More Important Than Simple Aging Period
The Type of Oak Barrel and Environment Used for Aging Matter

"Is whiskey with a higher aging period tastier and better whiskey?"

As interest in whiskey has recently increased, more consumers are curious about the correlation between whiskey and aging. The answer to the question of whether the aging period of whiskey is proportional to its quality is "half true and half false." It is true that whiskey with a longer aging period is more likely to have diverse and deep flavors, but it does not mean that whiskey with a shorter aging period is low-quality and tasteless.

The flavor of whiskey is directly related to aging. Besides the physical time, various factors involved in aging include the oak barrel, the quality and alcohol content of the raw spirit, the aging environment, the climate of the aging region, and the aging period. Among these, some factors have a significant impact on aging.

First is the oak barrel used for aging. Oak barrels are classified based on what type of liquor was stored in them before whiskey aging, assuming the barrel has been used at least once. They are categorized as sherry casks, port casks, bourbon casks, etc., each with distinct characteristics. These oak barrels retain the flavors of the previously stored liquor absorbed into the wood, which greatly influences the taste of the whiskey. In particular, nowadays, some whiskeys undergo additional aging in specific oak barrels during the finishing stage to impart unique characteristics. Whiskeys labeled as ‘cask finish’ or ‘sherry finish’ fall into this category.

Second is the climate and aging environment of the aging region. Whiskey aging is a chemical reaction, and chemical reactions generally proceed faster at higher temperatures. For example, the average annual temperature in Speyside, Scotland, the center of Scotch whisky production, is about 8.6°C. In Montreal, Canada, where the average annual temperature is lower (about 6.8°C), the aging process is slower, whereas in Taipei, Taiwan, where the weather is relatively warmer (about 23°C), the aging process is faster. The faster the aging process, the more whiskey naturally evaporates, so it is known that it is difficult to age whiskey for a long time in hot climates.

According to the Taiwanese whiskey brand ‘KAVALAN,’ the aging speed of whiskey in Taiwan is at least 4 to 5 times faster than in Scotland. KAVALAN has utilized these climatic conditions to produce differentiated whiskey with good taste, aroma, and flavor even after a short aging period. In fact, KAVALAN’s non-age statement (NAS) whiskeys have won more than 700 medals at prestigious international liquor competitions to date, overturning the common perception that whiskey must be aged for a long time to produce high-quality products.

An official from the domestic whiskey industry said, “In the past, because aging technology like today did not exist, products with a high aging period, which could generally be expected to have excellent quality, were recognized as premium. However, nowadays, technology has advanced to systematically understand the principles of aging and realize high-quality whiskey in a relatively short period.” He added, “We hope consumers will break away from certain prejudices or misconceptions and enjoy the diverse personalities and flavors that whiskey offers.”
